last one i had was an 04 nissan altima with like 22000 miles on it… i would say well maintained cause it was just at our shop for oil change.
but i def am curious about the 87-93 difference… cause i have thought this also. but hey if it works more power. i earn get go gift cards from AAA about 40 bucs every few months i just try to use them at giant eagle for free grub.
